In the MagicDraw SysML Plugin and Magic Cyber-Systems Engineer® (Cameo Systems Modeler®), for most types a nested Property symbol may be "dragged out" beyond the symbol of its immediate owner to create a so-called "shortcut" symbol with nested property path dot notation. This works also for Properties within Port symbols on the boundary frame of a diagram.
It does not, however, seem to be possible to create such a shortcut symbol fully within contained (surrounded by) the diagram frame (which might be a problem with some of the SysPhS specification diagram representations).
